A TfmA/Ey United States Patent 3,105,641 ANTI-SPLASH GASOLINE PUMP NOZZLE ADAPTER Michael Curcio, 168-17 Cryders Lane, Whitestone, N.Y. Filed Sept. 29, 1961, Ser. No. 141,906 1 Claim. (Cl. 239-552) This invention relates to an anti-splash gasoline discharge adapter for use with a gasoline pump hose nozzle.

It is the principal object of the present invention to provide an anti-splash discharge nozzle adapted for use on the hose nozzle of a gasoline pump which will so alter the flow discharge of the gasoline from the gasoline pump nozzle that instead of discharging in a solid stream which spreads outwardly to the side walls of the vehicle gasoline tank inlet pipe and closes off the same, will cause the flow of multiple streams of the gasoline so that air space is preserved within tank inlet between gasoline streams and the wall of the inlet pipe whereby air will be vented through the tank inlet from the tank to the atmosphere as the air within the tank is displaced by the gasoline being poured into the tank and the overflow and spilling of gasoline usually resulting therefrom will be minimized.

It is another object of the invention to provide a gasoline nozzle adapter for a gasoline pump hose nozzle which will maintain the even flow of the gasoline being supplied to the vehicle fuel tank from the gasoline pump without surging and without the discharge flow from the pump nozzle being greatly impeded, the flow being divided into streams by thin wall structures.

It is still another object of the invention to provide an adapter for a gasoline supply pump nozzle that can be readily fitted upon the end of the pump nozzle in a simple slide fit manner up only to a mid-point thereof and wherein the multiple streams of the gasoline are effected by thin interfitting cross pieces arranged in two parts with one part overlying and angled from the other, and the assembly located at the outlet end of the adapter whereby the solid stream of gasoline being forced through the pump nozzle will be divided into multiple streams as it leaves the adapter allowing air to pass upwardly between them.

It is a further object of the invention to provide an adapter for use upon a discharge nozzle of a gasoline pump hose in which the assembly causing the breaking up of the stream of gasoline is formed of interfittecl crossed pieces, forming square discharge openings in the center of the adapter that surrounded by openings in the assembly are of less area than the squares so that larger central streams will be surrounded by lesser area streams FIG. 3 is an enlarged discharge end view looking upon the thin crossed piece assemblies,

FIG. 4 is a vertical sectional view of the nozzle and adapter as viewed on line 4-4 of FIG. 3, and

FIG. 5 is a collective and perspective view of one of the crossed wall piece assemblies, the manner in which they are interfitted being thereby illustrated.

Referring now to the figures, 10 represents a hose through which gasoline is dispensed from the gasoline pump and which has a hand valve 11 with a long nozzle 12 extended therefrom. The nozzle 12 is in the form of a pipe bent at its end andcan be extended up to its stop collar 13 into a vehicle fuel tank inlet pipe 14 that extends upwardly and outwardly from a fuel tank, not shown. This nozzle 12 is usually bent at its end and a solid stream of gasoline is discharged therefrom that spreads out as it is passed through the pipe striking against the wall of the inlet pipe especially in places where it is curved so that it tends to close off the pipe whereby air which has to be displaced by the gasoline is unable to vent through the pipe 14 to'the atmosphere. As a result splashing and spilling of [the gasoline usually occurs.

and thereby provide for a greater breaking up of the stream close to the wall of the tank inlet pipe whereby the greater tendency to stoppage of air being vented is most prevalent.

Other objects of the invention are to provide an adapter for a gasoline fuel pump nozzle, having the above objects in mind, which is of simple construction, formed of a minimum number of parts, easily assembled, inexpensive,

compact, easily fitted upon the gasoline pump nozzle and.

. inlet pipe as when gasoline is being directed into the fuel tank from a gasoline pump,

FIG. 2 is an enlarged fragmentary elevational view of the adapter fitted upon the end of the pump nozzle,

By the use of a present adapter 15 fitted on the bent end of the nozzle 12 and constructed in a manner to be presently described, the tendency for the gasoline to splash and overflow is minimized. This is done by breaking up the solid stream into multiple streams of the gaso line so that air can pass upwardly betw een them and not be obstructed by the flow of the gasoline.

The present adapter 15 comprises a thin sleeve 16 that is slidably and tightly fitted to the bent down end of the gasoline pump nozzle 12. This sleeve is made of metal "similar to the metal of the nozzle 12 and can be retained against accidental displacement of the nozzle 12 by solder disposed between the nozzle and the sleeve. The sleeve "16 has, intermediate its length, an internal annular stop rib 17 that abuts the end face of the nozzle 12 and limits the extent to which the adapter can be fitted over the nozzle and protects cross piece mesh assemblies 18- and 19 in the lower end of the sleeve 16 that, in turn, are tight fitted and soldered thereinto.

Each of these upper and lower cross piece assemblies 18 and 19 are constructed in the same manner of a series of diiferent length plates 21 and 22, two sets for each assembly, and in-tei'fitted with one another by slots 23 and 24 lying respectively in upper edges of the lower set of the plates and in the lower edges of the upper set of plates. The long plates of each set are indicated at 21 of which there are two for each set, and the short plates indicated at 22, also of which there are two for each set. The long plates 21 have four assembly slots while the long plates have two assembly slots.

The arrangement of these plates are best seen in FIG. 5 prior to their assembly together and upon being assembled as shown in FIGS. 3 and 4, they cross one another and provide square openings 25, nine in number, immediately about the center of the assembly and in connection with the sleeve 16 surrounding these square openings 25, a series of nine less area openings 26 making thereby for a total of eighteen openings for each assembly. Both mesh assemblies 18 and 19 are of similar construction. The lower assembly 19 is located at the lower end of the sleeve 16 and slightly out at the bottom thereof. The upper assembly 18 is located above and upon the assembly 19 with the lower edges of its plates engaging with the upper edges of the lower assembly 19'.

The lower assembly 19 likewise has eighteen openings,

into eighteen streams and these same streams may again be broken up into the final stream 2% from the lower cross piece assembly 19. The assemblies 13 and 1? are angled about a center axis from one another approximately forty-five degrees and thus as a result thereof the thin plates of the respective assemblies are angled. The opening of both assemblies are viewed in a composite manner as in FIG. 3 and from this it will be noted that there are more openings than the eighteen of the upper assembly, thereby making for a still further number of streams of gasoline varying in area from small to large size streams but allowing for air to flow upwardly between them. The gasoline upon passing into the inlet pipe is thus thoroughly dispersed so that air that is displaced from the fuel tank can flow outwardly through the inlet pipe 14- between the streams and into the atmosphere without putting stoppage-to or causing splashing or overflow of the gasoline being delivered to the fuel tank from the pump nozzle 12 through the inlet pipe 14.

In one side of the nozzle 12 is a hole 31 that serves as an air vent inside the end of the nozzle 12 so that a small quantity of air is sucked into the solid stream of gasoline which serves to form bubbles, which in conjunction with the batlles 1S and 19 assist in breaking the gasoline into a multiplicity of fine streams. In order that this hole 31 will not be covered by the adapter when fitted upon the nozzle, a notch opening 32 is provided in the upper edge of the adapter sleeve 16. When the adapter 15 is applied to the nozzle 12 the notch opening 32 will overlie the opening 31 in the gasoline pump nozzle 12. Air drawn through opening 31 is readily diffused through the streams of gasoline and discharged between the inner wall of pipe 12 and the outer wall of adapter 15 together with air displaced from the gasoline tank by the inflow of gasoline. It should now be apparent that there has been provided an anti-splash adapter which can be applied to the gasoline pump nozzle whereby the gasoline upon being supplied to the inlet pipe of the fuel tank will not obstruct the outward flow of the air from the fuel tank as it is displaced by the gasoline being supplied thereto. The flow of the gasoline into the tank is broken up within the inlet pipe so that there is no closing off of the inlet pipe that results from a solid stream that would cause the gasoline to surge, and splash from the inlet pipe upon filling the vehicle tank.

While various changes may be made in the detailed construction, it shall be understood that such changes shall be within the spirit and scope of the present inven tion as defined by the appended claim.

What is claimed is:

In combination with a gasoline line having a hose and a nozzle adapted to be inserted in the filling opening of a gasoline tank, an adapter for breaking the solid stream of gasoline emanating from said nozzle into a multiplicity of small streams whereby to permit passage of air in said gasoline tank displaced by the introduction of gasoline to pass through and between said small streams andout of said filling opening to the atmosphere to reduce splashing overflow and spilling normally occasioned by the disrup-f tion of a solid stream emanating from the nozzle by air bubbles escaping therethrough, said adapter comprising a sleeve secured about the end of said nozzle, an annular stop rib in-termediately located in said sleeve, and a pair of stream breaking mesh assemblies positioned between the outer end of said sleeve and said rib, each of said assemblies comprising a plurality of slotted plates interfitted in night angular relation to each other and extending transversely across the interior of said sleeve, with the platesof one mesh assemblybeing disposed at substantially angles to the plates of the other assembly,

said assemblies being superposed axially of said nozzle.
